Polymer passivation of defects in inorganic perovskite solar cells

Rational design of formamidine tin-based perovskite solar cell with 30% potential efficiency via 1-D device simulation

“…At the same time, the appropriate CBO between the absorber layer and the ETL also positively affects the photovoltaic performance. [55][56][57]…”

Efficient inverted perovskite solar cells with a low-temperature processed NiOx/SAM hole transport layer

“…7 Among various PSCs with different structures, inverted PSCs with p–i–n structure have received widespread attention due to their simple preparation process, weak hysteresis, no need for high-temperature calcination, and compatibility with stacked devices. 8,9 More importantly, after improving the crystallization of perovskite (PVK), 10–12 passivation defects, 13,14 and implementing interface engineering, 15 the efficiency record of inverted PSCs has been significantly improved, almost comparable to the regular n–i–p structure.…”

Effectiveness of poly(methyl methacrylate) spray encapsulation for perovskite solar cells

“…Solution processed PMMA encapsulation has largely taken the form of spin-coated encapsulation layers for perovskite and organic solar cells [20,21]. PMMA has also shown promising potential as an interlayer to passivate defects in perovskite films [22]. A PMMA interlayer was recently added to PSCs via spin coating to improve the device efficiency and stability in leu of a Copper(II) 2, 9, 16, 23-tetra-tert-butyl-29H, 31H-phtalocyanine (CuPc) hole transporting layer [23].…”
